Bug Report Problem with webcam. Wiggly lines in the video of cam.

First off my cam isn't actually a webcam, it is a Sony Handycam HDR-CX190. I know this wouldn't be a problem with an actual webcam but why not have a camera that can be used as a camera for videos and a webcam?

Anyway, I know what is causing the problem and it is the fact that my camera only goes to 30 (29.97) fps but OBS always renders it at a higher FPS than that and even when I manually type in 29.97 in Video Capture Device source properties it still has the wiggly lines. The only reason I know this is because in AmaRecTV (which is the software that I am using to capture the inputs on my AverMedia capture card) shows the source at 29.97 fps with no wiggly lines. But when I bump it up to 50 for 59.94 it has the lines.

So is there any way I can set the source of my camera in obs to 29.97?

You mean interlacing? Unfortunately the app doesn't natively support deinterlacing, which is what causes those wiggly lines you see. Routing through amarec is currently what most people do, which is.. well, to me unacceptable. I really need to get deinterlacing in, but I haven't even had time to do anything lately.

Hmmmmm, that didn't seem to fix it though I noticed something while messing with the resolution in OBS;
Basically if I try to make the picture from my cam smaller to fit in between the gaps of the LoL hud (or just a general small res) it has the wiggly lines. But if I leave it at the res that OBS set it to it is fine, but very large and will consume a lot of my screen on league.

EDIT: I also experimented with xsplit and it seems at 1280x720 all I have to do is enable the "Enhance Resize" option in the camera source and it cleans up all the lines, but when I switch the output res to 1920x1080 the lines come back rather I have the option ticked or not.

Right click your camera source, Go to properties, and change the resolution (size) of your webcam there. This will change the downscale method and should eliminate the artifacts you are seeing.

I actually had to tick the custom resolution box and put the resolution at 720x480 because that is what I have it set at in AmaRec and without that there would be a bunch of green under the video. (I am assuming that is space that is not being taken up by the camera's video and it is having a problem.)
